New research by scientists at the University of Nottingham suggests that environmental contaminants found in the home and diet have the same adverse effects on male fertility in both humans and in domestic dogs.

There has been increasing concern over declining human male fertility in recent decades with studies showing a 50% global reduction in sperm quality in the past 80 years...

DGIST research team succeeded in developing a microrobot that can reach the accurate location of cardiovascular disease such as the Chronic Total Occlusion by moving and steering the microrobot towards a desired direction inside complicated blood vessels. This research is expected to increase the success rate of treatment and shorten the time of cardiovascular disease surgery.

DGIST announced on February 27 that Professor Hongsoo Choi’s team in the Robotics Engineering Department developed the ‘Magnetically Controlled Microrobot’ that can enhance the success rate of CTO treatment among myocardial infarctions through a...

A popular theme in the movies is that of an incoming asteroid that could extinguish life on the planet, and our heroes are launched into space to blow it up. But incoming asteroids may be harder to break than scientists previously thought, finds a Johns Hopkins study that used a new understanding of rock fracture and a new computer modeling method to simulate asteroid collisions.

The findings, to be published in the March 15 print issue of Icarus, can aid in the creation of asteroid impact and deflection strategies, increase understanding of solar system formation and help design asteroid mining efforts.

“We used to believ...

New material could mean fewer trips to the dentist’s office, scientists report. A compound used to make car bumpers strong and protect wood decks could prevent return visits to the dentist’s office. A team of researchers with the OHSU School of Dentistry in Portland, Oregon, have created a filling material that’s two times more resistant to breakage than standard fillings, according to a study published by the journal Scientific Reports. The new filling uses the additive thiourethane, which is also in protective coatings for cars and decks.

The team also has developed an adhesi...
